The guys who do the "Bad Lip-Reading" series on YouTube might have released their dumbest video yet.

It's Beyonce doing the "Star-Spangled Banner" at the inauguration, but with some other singer's audio dubbed in, so it looks like she's singing a bunch of nonsense.

If you only watch 30 seconds, watch 1:40 to 2:10

You can see more of their hysterical...and stupid...videos HERE!
